概要	Multiple case-based netnography combines Kozinets's netnographic method — an ethnographic adaptation for online communities — with Yin's multiple case study logic. The researcher systematically collects and interprets naturalistic digital data from two or more distinct online communities or platforms, then conducts within-case analyses and a structured cross-case comparison to identify both shared patterns and context-specific differences. The design is especially powerful for understanding how cultural meanings, consumer practices, or social dynamics vary across different digital contexts.	Ethnography is a qualitative research tradition in which a researcher immerses themselves in a social group or community over an extended period — typically three to six months or longer — to study its culture, values, and behaviours in their natural setting. Originating in social and cultural anthropology, and consolidated as a rigorous method by Bronisław Malinowski in the early twentieth century, ethnography produces rich, contextualised accounts of how people live, work, and make meaning together.
